We are offering the Pennsy X29 boxcars with patch panels in the mid-1950s Merchandise Service scheme. "Merchandise Service" was the Pennsylvania Railroad's less-than-carload (LCL) service, inaugurated in the 1940s to compete with the fast-growing post-war trucking industry. Four PRR car classes were used for this purpose, each specially-lettered to advertise this service. The initial lettering arrangement featured a full-length silver/aluminum band with white and red accents. Soon thereafter, this colorful scheme was simplified to all-white by replacing the silver areas with white and the red areas with standard freight car color. The X29 was the only class of the four never to carry the silver-band scheme. During the mid-1950s, the Pennsylvania Railroad adopted a "billboard" lettering scheme for its rolling stock featuring a more prominent road name and a large keystone logo accented by a black shadow. At this time, the "Merchandise Service" lettering arrangement was revised to incorporate these features.
